“…From 1970 to 1980, a wave of technological development based on computer mainframes began to appear, and its corresponding business model was dominated by automated data processing. With the advent of the client-server interaction concept in the 1990s [9], more and more users owned personal computers, which led to the development of new business models based on knowledge-based work and the restructuring of enterprise in various fields. In 2000, the concept of Internet 1.0 promoted the rapid development of B2B, B2C, e-commerce, and ERP.…”

With the implementation and development of China's digital economy strategy, the integration of the real economy and the digital economy has become a national strategy. The traditional textile manufacturing enterprise has gradually become the main direction of enterprise reform in the form of digital marketing. In the face of the increasing consumer demand of consumers and the gradually unbalanced market supply and demand of textile manufacturing enterprises in China, this paper uses the methods of generalization and case analysis to comprehensively expound the necessity of digital marketing reform for textile manufacturing enterprises from the aspects of policy, technology and industrial environment. According to the research results, it is necessary to construct a new path for future upgrading and development from the two dimensions of industrial upgrading strategy and universe marketing layout based on different perspectives of textile manufacturing enterprise management reform, and to shape a closed loop of digital marketing, thus further promoting the deep integration of digitization technology and textile manufacturing enterprise.

“…Furthermore, the chromatic and the polarization mode dispersion are reduced [7]. A single carrier signal's capacity can be doubled by polarization multiplexing, followed by polarization diversity optical coherent detection [8]. Very recently, Dual-Polarization Quadrate Phase Shift Keying (DP-QPSK) is the most exciting technology.…”

The demonstration of a higher data rate transmission system was a major aspect to be considered by researchers in recent years. The most relevant aspect to be studied and analyzed is the need for a reliable system to handle nonlinear impairments and reduce them. Therefore, this paper examines the influence of Four-Wave Mixing (FWM) impairment on the proposed high data rate Dual polarization-Differential Quadrature phase shift keying (DP-DQPSK) system using the Optisystem software. In the beginning, the impact of varied input power on the proposed system's performance was evaluated in terms of QF and BER metrics. More power is used to improve system performance. However, increasing power would raise the FWM effects. Accordingly, a −10 dBm input power and the proposed system are used to reduce the impact of FWM. Additionally, a hybrid amplification method is proposed to enhance system performance by utilizing the major amplification methods of erbiumdoped fiber amplifier (EDFA): semiconductor optical amplifier (SOA) and Radio optical amplifier (ROA). The evaluation demonstrates that the OA-EDFA outperformed the other two key amplification techniques of (EDFA-SOA) and (EDFA-ROA) in improving Quality factor (QF) and Bit error rate (BER) system results for all distances up to 720 km. Consequently, the method contributes to minimizing the impact of FWM. In the future, other forms of nonlinearity will be investigated and studied to quantify their impact on the proposed system.

“…Now in terms of compensation of long-distance optical fiber transmission loss, the research is most based on the digital signal processing (DSP) linear damage compensation technology [10][11]. Such as the estimation and compensation of CD and PMD using DSP in electrical field, reference [12] Fabian N. Hauske from HUAWEI. In reference [13] 40 Gbit/s QPSK signal polarization multiplexing transmission was used in single-mode fiber (SMF) for 100 km, signals received are processed via A/D conversion offline DSP.…”

This paper introduces the DP-QPSK modulation coherent reception technology,the overall design and other key is sues for 100 Gbit/s DP-QPSK modulation. Using the technologies based on DSP, it realizes the long-range transmissions of 100 Gbit/s optical systems to achieve optical signal dispersion compensation, polarized solution reuse and phase estimation. The effect of this scheme is verified with OptiSystem and the simulation results indicate that this with the help of DSP module for processing of the received signal, the last constellation is ideal and scheme is implemented simply and has high reliability, and it also has reference significance for the optimization of coherent optical detection. The results show that the technical plan is easy and reliable, which has reference significance on optimization of coherent optical detecting hardware.
